Does your player have a video out in the retail firmware?

Sure, but thats not really all that useful since TVs don't have USB ports, meaning you'd have to watch it on a PC which could just decode the files directly.

I don't think its possible to make an actual USB to anything but USB cable, so your "mini usb to A/V cable" is probably not a real USB cable, but rather something else using a similar connector.

i tried it on my camera and it worked as a slide show on my TV like it would normally as if through the camera I'm not sure how much speed its capable of but it seemed to do slide shows fine. if it couldn't handle video would it be possible to make one?
sorry if im not being clear enough by the way

Your camera is designed to send an analog signal to the pins corresponding to the RCA jacks in that cable when you put it in playback mode.  A standard USB device only sends and receives digital signals.  You shouldn't expect to be able to plug that cable into any other device and have NTSC video come out of the other end of the cable.

Incidentally, I just bought a cheap camera today that plays this multi-use game with the USB connector.

it has a box inbetween the cables, i think its probably a converter or something that changes the signal somehow

I doubt it.  It's probably just a ferrite bead unless you have some reason to suspect active components there.  Do you have documentation for this cable?  Is it not a cable for your digital camera?

If you wish to interface your DAP with a separate piece of hardware you need to know what that hardware does.  You can't just randomly start sending binary to it and assume that the two will play nice together.  If you want to use the USB port on the Gigabeat then you need to properly write digital data to the port.  Its conversion to NTSC video will rely on your delivery of properly formatted digital information (a sequence of bits) to a circuit that will do the conversion for you.  There's no DAC wired to the USB port internally in the Gigabeat so you won't stand any chance of getting a straight NTSC signal out of that port.

As I said above, since it plays video, its definitely not a USB cable.
